提出了一种采用垂直腔面发射激光器和空间光调制器的自由空间波分复用（WDM）传输系统，该系统采用16正交幅度调制正交频分复用调制信号，传输距离为17.5 m。在低噪声放大器和数据比较器的帮助下，每个光通道都获得了良好的误码率性能。这种光学自由空间WDM传输系统对于提供包括数据和电信服务的服务将是有吸引力的。
An optical free-space wavelength-division-multiplexing (WDM) transport system employing vertical cavity surface emitting lasers and spatial light modulators with 16-quadrature amplitude modulation orthogonal frequency-division multiplexing modulating signals over a 17.5 m free-space link is proposed and demonstrated. With the help of a low-noise amplifier and data comparator, good bit error rate performance is obtained for each optical channel. Such an optical free-space WDM transport system would be attractive for providing services including data and telecommunication services.
